Abstract
Description
Die Erfindung betrifft eine Radaufhängung nach dem Oberbegriff des Anspruchs 1.The The invention relates to a suspension according to the preamble of claim 1.
Die Spurführung eines Rades wird nach dem Stand der Technik gewährleistet:
- A) über eine mit einer Lenkung versehene Spurstange;
- B) über die elastokinematische Lenker-(Hebelverstellung) des Achssystems oder
- C) eine Kombination der Maßnahmen A) und B);
- D) über Fahrzeugblattfedern aus Stahl; oder
- E) eine Kombination der Maßnahmen B) und D).
- A) via a steering rod provided with a steering rod;
- B) via the elastokinematic handlebar (lever adjustment) of the axle system or
- C) a combination of measures A) and B);
- D) via vehicle leaf springs made of steel; or
- E) a combination of measures B) and D).
Es ist bekannt, passive Querblattfedern an Personenkraftwagen zur Substituierung der Aufbaufeder und des Stabilisators einzusetzen (siehe z. B.: 1988 GM-10; 2004 Corvette).It is known passive transverse leaf springs on passenger cars for substitution the build-up spring and the stabilizer (see eg: 1988 GM-10; 2004 Corvette).
Solche aus Verbundwerkstoffen wie GFK bestehenden Federn werden bisher ausschließlich in vertikaler Richtung bzw. Z-Richtung beansprucht und übernehmen keine Radführung in Achsrichtung (Y-Richtung) bzw. partizipieren auch nicht daran.Such made of composite materials such as fiberglass existing springs are so far claimed only in the vertical direction or Z-direction and do not take any wheel guidance in the axial direction (Y direction) or do not participate in it.
Ein Problem derartiger Systeme ist hauptsächlich die äußere Lagerung der Feder, welche an der hochbeanspruchten Außenseite der Feder angreift.One The problem of such systems is mainly the external one Storage of the spring, which on the highly stressed outside the spring attacks.
Radführende Querblattfedern aus Stahl gab es bereits vor mehr als 80 Jahren, diese hatten jedoch stets den Nachteil der relativ starren Anbindung in Längsrichtung, was zu einem sehr schlechten Fahrkomfort und teilweise einem unsicheren Fahrverhalten führte.wheel control Steel sheet springs already existed more than 80 years ago, However, these always had the disadvantage of relatively rigid connection in Longitudinal direction, resulting in a very poor ride comfort and partly led to an unsafe driving behavior.
In den 50er und 60er Jahren gab es die Kombination einer Stahl-Querblattfeder mit einem zusätzlichen Dreiecklenker. Diese Art der Konstruktion bildete somit eine „Doppel-Querlenker-Achse” (vergleiche Simca 1000 (1962–78), Trabant (1957–91) und Opel GT.In The 50s and 60s, there was the combination of a steel transverse leaf spring with an additional wishbone. This type of construction thus formed a "double wishbone axis" (see Simca 1000 (1962-78), Trabant (1957-91) and Opel GT.
Zum
technologischen Hintergrund werden noch die
Nach dem Stand der Technik bestand nicht die Möglichkeit zur Nutzung der bisherigen Querblattfedern zu weiteren Funktionen insbesondere bei der Spur- und der Wankbeeinflussung.To The prior art was not the opportunity to Use of the previous transverse leaf springs for other functions in particular in the track and the Wankbeeinflussung.
Die Erfindung setzt beim Erkennen der vorstehend genannten Probleme des Standes der Technik an.The Invention sets in recognizing the above-mentioned problems of the prior art.
Die Erfindung hat die Aufgabe, diese Probleme möglichst weitgehend zu beheben.The Invention has the task of these problems as much as possible to fix.
Die Erfindung löst diese Aufgabe durch den Gegenstand des Anspruchs 1 und nach einer weiteren Erfindung durch den Gegenstand des Anspruchs 14.The Invention solves this problem by the subject matter of the claim 1 and according to a further invention by the subject-matter of claim 14.
Erreichbar sind derart je nach Ausgestaltung einer oder mehrere folgender Vorteile:
- – eine Reduzierung der Bauteilanzahl;
- – eine Reduzierung des Fahrzeuggewichtes und damit ein positiver Beitrag zur CO2 Reduzierung;
- – eine Übernahme von Radführungsaufgaben;
- – eine Substitution von radführenden Lenkern;
- – eine Substitution des Querblattstabilisators; und
- – eine Kostenreduktion
- - a reduction in the number of components;
- - a reduction of the vehicle weight and thus a positive contribution to the CO2 reduction;
- - an assumption of Radführungsaufgaben;
- - a substitution of wheel-guiding drivers;
- A substitution of the transverse leaf stabilizer; and
- - a cost reduction
Vorteilhafte Ausgestaltungen der Erfindung sind den Unteransprüchen zu entnehmen.advantageous Embodiments of the invention are the subclaims refer to.
Vorzugsweise wird die Querblattfeder aus einem Leichtbaumaterial, insbesondere aus GFK, hergestellt, was eine signifikante Gewichtsreduzierung gegenüber herkömmlichen Querblattfedern aus Stahl ermöglicht.Preferably the transverse leaf spring is made of a lightweight material, in particular made of fiberglass, which contrasts a significant weight reduction conventional transverse leaf springs made of steel allows.
Nachfolgend wird die Erfindung anhand von Ausführungsbeispielen näher beschrieben. Es zeigt:following the invention will be described in more detail on the basis of exemplary embodiments described. It shows:
